Pixel geometries for spatially multiplexed stereo 3D displays

Abstract

A 3D image pixel in a spatially multiplexed stereo 3D display includes a first left-eye subpixel and a second left-eye subpixel that are both driven when displaying the left-eye image. The 3D image pixel also includes a first right-eye subpixel and a second right-eye subpixel that are both driven when displaying the right-eye image. The subpixels may all have a square shape. Single color emitters in the subpixels of the same eye may be driven by the same electronics. A 3D image pixel in a second spatially multiplexed stereo 3D display includes a left-eye pixel driven when displaying the left-eye image and a right-eye pixel driven when displaying the right-eye image. The pixels may all have a rectangular shape, and the horizontal measurement of the pixels may be greater than the vertical measurement of the pixels.
